MetaMerge.Fody

Introduction

MetaMerge allows you to create patterns of .net attributes and apply them to multiple targets.

Goal

The aim of MetaMerge is to enable programmers to keep sets of attributes consistent throughout their application. For example, if there is a FamilyName property in a business object (server side) and also in multiple Contract classes (typically API data-transfer-objects) then we can ensure meta information such as MinLength etc are consistent across all of them.

public class Person
{
  [Meta(typeof(PersonFamilyName))]
  public string FamilyName { get; set; }
}

public class PersonDto
{
  [Meta(typeof(PersonFamilyName))]
  public string FamilyName { get; set; }
}

// The meta definition
public static class PersonFamilyName
{
  // The following attributes will be applied to
  // the target properties above.
  [Required, MinLength(2), MaxLength(32), Display(Name = "Family name")]
  public static object Target { get; set; }
}
